Ring Wave Generator - Square Wave Clock With Nothing But An Inverter Chip - Simply Put

- Опубликовано: 12 сен 2024
- There are so many ways to generate a square wave because they each serve different needs, such as power consumption, part cost and availability, board space, and engineering time. If you need a clean MHz range square wave that's reasonably stable but don't need it to have perfect regularity and can spare a few milliamps, you can make one with just a CMOS NAND chip. No resistors, no capacitors, no crystals, nothing: Just some logic gates.

Subbed for the hole in the headset, the posters and "Let's do something stupid!"
Stayed for the amazing clear explanations and interesting topics
You're a great teacher- looking forward to looking at more of your tutorials.
Nice! If I remember correctly, you can generate a sine wave with a transistor, or a couple of them and resistors, with feedback loop, based on transistor phase shift principle.
That sounds like a fun video to make.
I built something similar, but it used a resistor and capacitor. I used a CD40106 Schmitt-trigger Hex Inverter, and because of how the hysteresis works the RC allows you to control the square wave somewhat.
That's the same setup as you'd have with a 555 timer basically, just without the discharge pin hookup, because the 555 is essentially a schmitt trigger connected to a latch.
Ring oscillators are used to test propagation delays in digital blocks of ICs, since it is quite easy and cheap to use several logic gates to build these test structures
Never had much luck with the CD4069 for ring oscillation. I was using the unbuffered one. But the CD40106 makes great unstable squares for me to feed into CD4094s!
love your films, keep going
If you were *really* inclined to do so, you could use a CD4060 to divide the timer by whatever, and still keep chip count down.
Just recently came across this chip, and it seems kinda fun :)
Sounds like the basis for a cheap hardware random number generator. Exaggerating the inconsistencies into useful values would probably mean a microcontroller, but it could be really small. Maybe ATTiny 4/5/9/10 sized. I'll have to think about this.
very interresting, i will try it . so simple!
Cool. So by frequency we can calculate real propagation delay?
"Bucket"
I really need to do something with my bucket-brigade-devices!
I have a 3000w - 6000w peek generator that is produces a 240v modified sign. Is there a device that i can buy off of ebay / amazon that i can feed this source into that will output something close to a pure sign wave? Thanks
great info, thank you
5:00 What kind of headphone is that, no Speaker?
Good video thanks
Where is the square wave?
its just like minecraft
these are interesting vids but the really short cuts are more distracting than helpful :/
Look human, I like you but almost everyone needs a constant frequency, so thanks but no thanks... but I'm sure I will like all the other video's.
